Title: Improvements in and relating to the measurement of material on a conveyor
IPC: G01N23/12
Filed: 1964-08-04
Abstract: 1,078,831. Detectors. OHMART CORPORATION. Aug. 4, 1964 [July 29, 1963], No. 31192/64. Heading G1A. The weight of material on a conveyer is determined by an elongated radiation source and an elongated detector positioned across the width of the conveyer, with one above and the other below, the degree of radiation attenuation made by the material being proportional to its weight per unit length of conveyer: by correlating this with the speed of the conveyer the mass flow is found. The radiation source, which is housed in one arm of a tubular "C" frame, and in the embodiment described beneath the conveyer with the detector in the other arm above, is a ceasium 137 rod 44, shown in cross-section in Fig. 11, which is mounted in the inner lead shielding rod 42: by burning this rod, eccentrically mounted in the outer lead shielding rod 38, the radiation source is exposed through the collimator slit 49 whereby the detector receives radiation. The detector, of the type which produces a current when irradiated, is a number of parallel connected cells, one of which is shown in Fig. 12. The negative electrode, a brass or steel cylinder 80 coated in cadmium, magnesium or zinc, is mounted on end plate 78 making connection to earth 65 through rod 75 and end plate 70. The positive electrodes, brass or steel cylinders 85-86 coated in lead dioxide or colloidal graphite (electrochemically opposite to the negative electrode), has external terminals 74, 68, whereby several cells are connected in parallel. The assembly of cells is contained in a temperature controlled enclosure in the upper arm. The weight per area and mass flow recorders are calibrated in the absence of material by turning the source through about 90‹, the exact position having previously been determined and governed by a stop, which simulates a known weight of material on the conveyer. The detector may be of the type which changes its resistance when irradiated and both detector and source can be a series of spaced detectors and sources.
